UE Capability Signaling for Reliable Pre-Paging in Deep Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communications systems face challenges in effectively reaching user equipment (UE) located in deep coverage zones or obstructed areas, as conventional paging methods may fail due to signal attenuation or blockage.
Innovation Solution
The implementation of pre-paging techniques, where a network entity checks the UE's capability to process pre-paging messages during registration or through radio resource control (RRC) signaling, allowing for the transmission of pre-paging messages on dedicated resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional paging methods are used, then the system is simple to implement, but the ability to reach UEs in deep coverage zones or obstructed areas is poor
Solution Approach 1:
The network entity performs preliminary actions by obtaining UE capability information regarding pre-paging message processing during the registration procedure or through RRC signaling before actual paging is needed. This allows the system to prepare and configure pre-paging resources in advance, enabling reliable delivery to UEs in deep coverage zones without increasing operational complexity during the actual paging event.
2Reliability
If pre-paging capability information is obtained during registration or through RRC signaling, then the reliability of reaching UE is improved, but the signaling overhead and procedure complexity increase
Solution Approach 1:
The patent applies universality by integrating the pre-paging capability indication into existing registration procedures and RRC signaling flows that already occur during UE network entry. The capability information is obtained as part of the standard registration process or through existing RRC signaling exchanges, allowing one signaling mechanism to serve multiple purposes: confirming pre-paging capability while simultaneously completing the registration or connection setup procedure, thereby minimizing additional signaling overhead.
3Reliability
If dedicated resources are allocated for pre-paging messages, then the reliability of message delivery to UE is improved, but the resource allocation complexity increases
Solution Approach 1:
The system applies dynamics by configuring the network entity to allocate dedicated resources for pre-paging messages based on real-time UE capability information and coverage conditions. The resource allocation is dynamic and adaptive, allowing the network to adjust resource assignment according to the specific UE's pre-paging capability status and the current coverage environment, thereby optimizing delivery reliability without implementing a complex static resource allocation system.

AI summary
Certain aspects of the present disclosure provide techniques for user equipment (UE) capability handling for pre-paging. An example method, performed at a first network entity, generally includes obtaining information regarding a capability of a user equipment (UE) to process pre-paging messages, and transmitting signaling, after obtaining the information, indicating pre-paging information for a second network entity to transmit a pre-paging message to the UE on a first set of resources.
